Thank you for your purchase of a Spectra Catalina 340R system. When properly installed and
maintained, it will provide years of trouble-free service. Professional installaon is strongly
recommended. Like any piece of mechanical equipment, the system will require inspecon
and service, so plan ahead for service access and install “service loops” in cabling. If a dealer is
installing the system for you, review the locaon of the components to ensure the installaon
will meet your approval upon compleon.
Catalina Installation Quick Start
Important Details for Installer
1. The system must have a dedicated sea water inlet to guarantee a constant ow of water to
the system. The inlet should be as low in the boat as possible with a dedicated, forward-facing
scoop-type thru-hull ng.
2. Both the Catalina 340R feed pump module and the Clark Pump/Membrane module must be
installed in a well venlated compartment where temperatures will not exceed 113°F (45°C).
Many engine compartments exceed this temperature when underway. Warranty will be void if
the installaon does not meet this requirement.
3. Follow the wire gauge charts in the instrucons! Using larger wire than specied is
acceptable.
4. If you are separang the Clark Pump/membrane assembly, please review the high pressure
tube assembly instrucons. Improper assembly will cause failure!
5. Run, test, then sea trial the complete system before assuming it is operaonal. If the boat is
in fresh or dirty water, see Dry Tesng the System. Aer tesng, make sure the ush cycle
operates properly. The water going overboard at the end of the ush should measure <1000
PPM Total Dissolved Solids.
6. The Spectra Remote Manual control must have DC power connuously to achieve the full
benets of the fresh water ush system. The domesc fresh water pressure must be on and
the fresh water tank level maintained. Calculate about 7 gallons (27 liters) per ush.
7. The Spectra Remote Manual must be de-powered (DC power o) aer the system is pickled
or winterized.
8. Spectra dealers are responsible for educang the vessel owners on the operaon and
maintenance of the system. Please walk through the enre installaon with our customer.
9. The equipment owner should ll out the warranty card or register online.

Thru-hull Location: The system must be connected to a dedicated 1/2” to 3/4” forward facing
scoop-type intake thru-hull and seacock.
Install the thru-hull intake as far below the waterline and as close to centerline as possible to
avoid contamination and air entering the system. Do not install the intake close to, or
downstream of, a head discharge, behind the keel, stabilizer fins, or other underwater fixtures.
Thru-hulls in the bow area are susceptible to air intake in rough conditions. Sharing a thru-hull
can introduce unforeseen problems such as intermittent flow restrictions, air bubbles,
contaminants, and will void the warranty. For racing boats and high speed boats traveling above
15 knots, a retractable snorkel-type thru-hull fitting is preferred because it picks up water away
from the hull.
The brine discharge thru-hull should be mounted above the waterline, along or just above the
boot stripe, to minimize water lift and back pressure.
Avoid restrictions or long runs on the entire inlet side of the plumbing from the thru-hull to the
feed pump module.
Secure the piping away from moving objects such as engine belts and hatches. Prevent chafe on
the tubing as required. Test and inspect all piping and hose clamps after several hours of
operation.
Pipe Fitting Instructions: To seal plastic-to-plastic fittings, wrap 6 to 8 layers of Teflon tape
over their threads. Hold the fitting in your left hand and tightly wrap the threads clockwise. For
smoother assembly, do not tape the first (starting) threads.
Wiring
• Pay attention to wire size or system performance will be impaired
• Perform wiring to UL, ABYC, CE or applicable standards
• Avoid tight hose bends and excessive runs.
• Use heavy gauge wire.
• Install feed pump module as low as possible.
• Use a dedicated thru-hull with scoop type
strainer.

Components
Feed Pump Module
Mount the feed pump module on a vercal surface, up to 3-
feet (1.0M) above the waterline. It is preferable to mount as
low as possible. Locate in an area that allows easy access to the
lter, and the le hand side of the enclosure. Keep future
maintenance in mind when choosing a locaon, and do not
mount above water-sensive equipment. The feed pump has
overheat protecon and will not operate properly at
ambient temperatures over 113°F (48°C).
Sea Strainer and Boost Pump Module: Mount close to the
intake through-hull, below the waterline, in a locaon that
can handle water spillage during service. The boost pump
power cable will connect to the feed pump module.
Fresh Water Flush Module: The fresh water ush module may
be located in any convenient locaon near the feed pump
module. It should be mounted with the lter housing vercal
and accessible, with 2” of free space below the housing to
allow for lter changes. Do not install over electrical
equipment. The unit contains the charcoal lter, a solenoid
shut o valve, and a ush water ow regulator.

Customer-Sourced Tank Full Switch
Installing an oponal tank full oat switch at the top or the side of your water
tank allows the watermaker to ll your ship’s water tank then automacally
stop running. The user can then fresh water ush the system by hing ’Stop’
and then ’FWF’ on the Remote Controller.
Your watermaker does not come with the top-mounted Tank Full Switch
(EL-SWT-LV). However, this part can easily be sourced from your local
dealer or Full Service Provider if you wish for your system to
automacally stop once your freshwater tank is full.
If you do not install the Tank Full switch in your tank, you MUST
MANUALLY STOP the system when your freshwater tank has been lled. The system will not
stop automacally.
Note: The oat may need to be ipped 180 degrees to work properly. Many oats can be
easily ipped by removing the clip opposite the wire.
Optional Tank Switch - Cont.
Drill and Tap
Drill and tap a 1/8” NPT port into the top of the fresh water tank if using a top-mounted oat
switch or into the side of the tank if using a side-mounted oat switch. A top-mounted oat
can be installed on a tank access cover, or directly into the water tank. If installing on an
access cover, be sure to leave a service loop on the oat switch wiring to allow removal of the
tank access cover.

New System Start-Up and Testing
Avoid running the Catalina system if the vessel is in contaminated water. The system should be fully tested before leaving port.
If the location or weather prevents proper testing, refer to Dry Testing with an Artificial Ocean on page 29.
Every new system is shipped from the factory with nontoxic, food-grade propylene glycol. Propylene glycol,
Spectra Chemicals, or anything other than seawater or freshwater must be purged from the system with the
pressure relief valve open at least 1/2 turn. You can purge your system with seawater or with freshwater via the
system’s freshwater flush function. The system must be purged for a minimum of 60 minutes, or until at least 40
gallons of water have moved through the system.
***When purging SC-1 from a pickled watermaker, system must be purged for a minimum of 20
minutes. Propylene Glycol should be purged for minimum 60 minutes***
Warning! Damage may occur if the purge sequence is bypassed
and the membrane is pressurized with storage chemical in it.
1. First, check that:
• Thru-hull inlet and the brine discharge valves are open.
• All of your hose connections are tight.
• The washer with the green tag under the pressure relief valve has been removed.
• The pressure relief valve is open at least 1/2 turn.
• The sampling valve is set to the sample position
• The brine line is able to freely discharge
3. Run the system without pressure for 60 minutes to purge the storage
chemicals. The pressure gauge should read less than 35 PSI. If purging with
freshwater, the sampling tube may discharge water.
4. Close the pressure relief valve. The pressure should rise to 60-80 PSI (4.2-5.7bar) on a
Catalina 340R. Water should begin to flow out of the sampling tube. If the ship is located in
brackish or fresh water, the pressure will be lower.
Depending on storage and environmental conditions the system may need to have additional
purging time. If the product water does not taste pure or sample at below 500 ppm, purge or run
the system with the pressure relief valve open for up to 6 additional hours.
Open 1/2 Turn when
purging chemicals!
Remove Tag and Washer!
For a purge with seawater
• Move to an area free of contaminated water.
Avoid areas such as polluted harbors or canals.
For a purge using the freshwater flush
• The vessel’s pressurized water system
is on
3-Way Sampling Valve
2. Turn on feed pump via the manual toggle switch and check to
make sure water is coming out of the brine discharge (thru-hull

Dry Testing with an Artificial Ocean
If it is not possible to test run the system with the boat in the water, you may test the system with
an artificial ocean. You will need 1.3 lbs. of non-iodized salt (rock salt, sea salt, or aquarium salt)
to make a 5 gallons (33 grams of salt per liter) of water that is about 33,000 PPM salinity (average
seawater salinity). Make sure the domestic water system is powered up and the boat’s tank has at
least 60 gallons (230 Liters) of water to purge the storage chemicals from the system. Confirm
that the charcoal filter is installed in the feed pump module, and the domestic water line is
connected.
1. Open the pressure relief valve on the Clark Pump. Remove the green tag and spacer.
2. Press the Fresh Water Flush (FWF) button to run a full flush cycle. Do this six times to
purge the storage chemicals, a 36 minute process.
3. Replace the brine overboard hose with the brine service hose per Figure 3.
4. Push the Fresh Water Flush (FWF) button again to fill the bucket with fresh water from the
brine discharge service hose (hose attached to Clark Pump). Press Stop when the bucket is
full.
5. Mix the salt to the proper proportion or use an aquarium hydrometer to adjust the salinity level
to a specific gravity of 1.025.
6. Disconnect the quick release fitting from the pigtail coming from the charcoal filter housing
outlet and connect the intake service hose per Figures 4. Route both service hoses into a 5
gallon (20 liter) bucket. Disconnect the product tube from the diversion valve manifold, and
using another small piece of tube, route it into the bucket.
7. Push the Start button, allow the system to prime, and then close the pressure relief valve. The
system should build pressure shortly and start making water, with the brine and product water
recombining in the bucket to be cycled again. This will gradually heat the water. Do not let the
water temperature exceed 120 deg. F (49 deg. C). Run the system for roughly 45 minutes of
operation.
8. While the system is running pressurized, check for proper operation and leaks. After testing
the system, re-install the brine discharge hose, product tube, and fresh water hose from the
strainer. You can now flush the system by pressing the Fresh Water Flush button.

If the system has been pickled, winterized, this is the rst startup, or the condion of the system is
unknown, go to NEW SYSTEM START-UP on page 28 or serious damage may occur.
A fresh water ush should be performed aer every use of the watermaker. The system will need
to run for approximately half an hour to make enough fresh water for one ush.
Fresh Water Flush (FWF)
Pressing the ‘Fresh Water Flush’ (FWF) buon
oods the watermaker with fresh water from the
vessel’s domesc water tanks. Opens solenoid
valve to allow water to ow from tank instead of
seawater from the thru-hull. Fresh Water Flush
mode will end automacally aer ush is
complete, approximately 3 minutes.
Stop
Pressing the “Stop” buon ends watermaker opera-
on. The “Stop” buon must be pressed before
beginning a Fresh Water Flush.
Fault Light
The “Fault” light indicates that there is a
problem with the system. This relates to a high
pressure or boost pressure fault, read by the
vacuum switches aached to vane pump.

Flush Adjustments
Adjustments for your Catalina 340R are typically calibrated from the factory to ensure that sea
water is thoroughly ushed out of the watermaker using the least amount of fresh water.
However, due to dierent lengths of hose runs, dierent rates of ow, and dierent pressures
in shipboard fresh water systems, the ush duraon should be opmized for your boat. The
ush cycle is adjusted with 2 sengs: the pump speed and the ush duraon.
Check the pump speed
1. Close the thru-hull for the raw water inlet.
2. Push the Fresh Water Flush (FWF) buon. The ush valve will open and the feed pump will
start at Flush Speed. If the ush completes normally, then the Flush Cycle is set properly.
Slowing down the pump during a Fresh Water Flush
Inside the feed pump module, next to the Control Box, is the pump speed controller. On the
speed controller board are two magnec reed switches for adjusng
the pump motor speed. The switches are narrow black bars,
5/8” (16mm) long. The increase speed switch is labeled S2; the
decrease speed switch is labeled S3. Each me a small magnet is
placed near the switch with the pump
is running, the speed will change slightly.
1. Open the thru-hull for the raw water inlet.
2. Push the Fresh Water Flush (FWF) buon.
3. Gently tap a magnet on the S3 Reed Switch (Decrease Speed
Switch). Wait 3 seconds between each pass of the magnet.
4. Gently tap the magnet 3 mes, then go back to step 3.
Once you’ve adjusted the speed correctly, the speed controller
will stay programmed for this speed during fresh water ushes.

ushing.
Allow the fresh water ush to connue to compleon. At the end of the ush cycle capture
some of the ush water at the brine discharge in a clean cup. Measure the salinity of the brine
discharge and conrm that it is below 1000ppm using a calibrated hand held TDS meter.
If the ush duraon needs to be increased, connue reading.
Adjusting Fresh Water Flush Duration
The Catalina Freshwater Flush Duraon is set to a factory default of 3 minutes, which is usually
the right amount of me to ensure that seawater is thoroughly ushed out of the watermaker
using the least amount of fresh water. However, due to dierent lengths of hose runs,
dierent rates of ow, and dierent pressures in shipboard fresh water systems, the ush
duraon can be opmized for your boat.
Set the Flush Duraon with a small screwdriver so that the fresh water ush comes to an end
just as the salinity of the brine discharge drops below 1000 PPM, or no longer tastes brackish.
Since the ush duraon can only be adjusted in round minutes, you may want to lessen the
duraon to 2 minutes, to save water, or increase to 4 or more minutes to ensure a thorough
ush.
Also, the charcoal lter is rated for 1.5 GPM (6 LPM): If the system pushes more than 1.5 GPM
through the charcoal lter

If the system has been pickled, stored, or contains cleaning compounds, use the New System Startup procedure.
The system should be fully run tested before you leave port. If the location or weather prevents proper testing refer to
“Testing with an Artificial Ocean.”
1. Check that the thru-hull inlet is open.
2. Turn the product sample valve to the SAMPLE position.
3. Turn the toggle switch on the feed pump module to RUN MANUAL.
4. Start the system by pushing ‘Start’ and check for flow by inspecting the brine discharge and checking
for pressure on your analogue gauge. If there is no flow, open the pressure relief valve on the Clark
Pump to prime the system and bleed the air out of the feed pump.
5. After 5 minutes, check the product water with your handheld salinity tester. When it is below 750 PPM,
divert the product into your tank by rotating the product sample valve handle 90 degrees.
6. Run the system until you have filled your tank or have made enough to meet your requirements.
7. Following your water making session, perform a freshwater flush.
Freshwater Flush (You should freshwater flush your watermaker after EVERY use.)
1. Push the Freshwater Flush button on the remote panel.
2. The freshwater flush solenoid will open and feed pump will come on, allowing pressurized freshwater
to flow through the system. Pressure will drop on the gauge, which indicates that the membrane is
flooded with fresh water.
3. After a proper flush, the ppm of the brine discharge should be below 1000ppm.
You may now leave the system unattended for up to five days (30 with the Z-Ion) without further attention.
Remember that you need to run the system almost a half an hour to make enough water for a flush. You
may notice that the system output is higher while charging your batteries, as the machine is voltage
sensitive.

Maintenance
General
Periodically inspect the entire system for leakage and chafing. Repair any leaks as
soon as you find them. Some crystal formation around the Clark Pump blocks is
normal. Wipe down any salt encrusted areas with a damp cloth.
Watermakers are at their best when run regularly. Biological fouling in the membrane is more
likely when a watermaker sits idle. A warm environment will cause more growth than a cold
environment. A fresh water flush every five days will greatly reduce biological growth, but may
not stop it completely. The Z-Ion system protects the membrane from bio-fouling without the
use of storage chemicals and can be flushed every 30 days for maximum effectivity.
The Seawater Strainer
The seawater strainer’s stainless steel element should be inspected, removed, and cleaned as
needed. Ensure that the thru-hull is closed before disassembly and the gasket is in place before
reassembly. When the system is put into storage, remove the strainer, rinse with fresh water,
and reassemble dry to impede corrosion. Check frequently during operation.
Prefilter Assembly
Prelter elements must be changed frequently. The rate is solely dependent on the input water.
A 5-micron lter might last you a 4-6 weeks in clear open ocean seawater, or be ruined in
minutes in a dirty harbor. A vessel may be sailing through seemingly super clear water, but
cruise through a plankton bloom and the prelter will be ruined. Spectra does not advise to
aempt to clean dirty prelters. Prelters are a consumable item and should be changed for
new when in queson. Please review prelter bullen to page 50. prior to running your
system.
To service the lter close the thru-hull, open the prelter housing, remove the old lter, clean
out the housing bowl, and reassemble the housing with a new 5 micron lter element. Leave dry
unl next startup.
Note: Use only Spectra-approved lters or you may void your warranty. Occasionally, lightly
lubricate the O-rings with silicone grease.
Oil/Water Separator (Optional)
To install oil water separator capability, add a second lter housing UPSTREAM of the 20 and 5
micron housings. Service as you would per the instrucons above.

35
The Charcoal Fresh Water Flush Filter
Replace the charcoal filter element at least every 6 months. This filter protects the membrane
by removing chlorine from the flush water. Use only a Spectra-approved replacement.
The Feed Pump and Clark Pump
The feed pump and the Clark Pump require no routine maintenance except inspection for
leaks. Tighten any hose clamps or fittings that show signs of leakage. The high pressure fittings
threaded into the Clark Pump have O-ring seals with a straight thread. These should never leak
and should never be over-tightened. If one of the tube nuts starts to leak, it can be un-
threaded, sealed with a bit of silicone grease or oil, and tightened with two wrenches very
tightly.
The Membrane
Membranes are susceptible to mineral scaling, biofouling and oxidation damage. The leading
cause of fouling is biological growth that forms when the system is left unused without
flushing or pickling. Fouling from mineral scaling can happen under certain seawater
conditions, or from rust. Oxidation damage can occur if the membrane comes into contact
with any strong oxidant, such as Ozone, Chlorine, etc. Monitor the product salinity and feed
pressure for higher than normal readings, take environmental conditions into consideration.
Note:
• Cold feed water or a higher salinity seawater source can cause high pressure.
• Low product flow is usually due to low voltage, a worn feed pump, or worn Clark Pump.
Due to the unique design of your Spectra system, low product water volume is typically not a
membrane problem, but frequently related to low voltage, a worn feed pump head, or a worn
Clark Pump. Always perform a flow test before cleaning your membrane.
Test to see if biological growth has occurred: Before running the system, remove the
prelters and examine their condion. If the lter housings are full of smelly, discolored water,
the system was not properly stored. Install clean prelters.
Next check the membrane. Detach the brine discharge hose, aach the brine service hose, and
lead it to a bucket. Open the pressure relief valve 1/2 turn, and manually run the system for 30
seconds (metal toggle switch on feed pump module). Examine the brine water: If it is
discolored and smells bad, perform an SC-2 cleaning with unchlorinated water before running
the system pressurized. If the brine is fairly clean, follow the New System Startup procedure
on page 28 and run normally. Check for performance. Clean the membranes only if
performance is reduced.
See the Cleaning Procedure for complete instructions.
Maintenance - Cont.

Leaking Fings
The system has eight high pressure ngs, two on each cylinder on the Clark Pump, two on
the pressure vessel end caps, and two 90-degree elbows on the back of the Clark Pump. As the
compression ng is ghtened, it compresses a ferrule onto the stainless tubing, xing the
ferrule permanently to the tube and holding the compression nut capve.
The body of the ng seals to the underlying component with an O-ring. On the Clark Pump
cylinders and the end caps this O-ring is compressed by ghtening the enre ng. The O-
rings on the 90-degree ngs on the back of the Clark Pump have capve nuts and washers,
which compress the O-rings without turning the enre ng.
If a tube ng leaks it can somemes be resealed by just ghtening. You must use two
wrenches, a 13/16-inch wrench to hold the base, and a 7/8-inch wrench to turn the
compression nut. The 13/16-inch wrench will need to be thin so as not to interfere with the
compression nut. If this doesn’t work, disassemble the ng, grease liberally with silicone
grease (the ferrule and the threads) and re-ghten rmly.
The base O-rings should be gently compressed to achieve a good seal, and may be damaged
by overghtening.

Introducon to Spectra Chemicals
We use four types of chemicals: SC-1, SC-2, SC-3, and propylene glycol anfreeze. SC-1 and
propylene glycol are for system storage, while SC-2 and SC-3 are for membrane cleaning. Do
not use sodium-bisulfate, citric acid, or any other storage chemical not supplied by Spectra.
These chemicals, used to store other watermaker brands, will damage the Clark Pump,
membrane end plugs, manifolds, and other components. Using non-Spectra chemicals will
void the warranty.
Note: Never use any chemicals with the system pressurized! Always open the pressure relief
valve 1/2 turn. Always follow the instrucons for purging the chemicals as shown in the New
System Startup secon (page 25).
Storage
SC-1 prevents biological growth when your system is idle. It should not be used as a cleaning
chemical, nor will it protect your system from freezing. A bag of SC-1 is mixed with 1 to 2
gallons of product or dechlorinated fresh water in a bucket and circulated through the system
for 10 minutes. This treatment will protect the system for six months, aer which the SC-1
treatment must be repeated. To use SC-1, follow the instrucons for Storage Procedure.
Spectra systems should be stored with propylene glycol if freezing is likely to occur. Propylene
glycol can be used instead of Spectra SC-1 storage chemical for storage in any climate, and
treatment is eecve for one year. Propylene glycol is a food-grade anfreeze used to
winterize RV’s, boats, and cabins. Do not use ethylene glycol automove anfreeze, which is
toxic and will damage the system.
The propylene glycol formulaons sold in marine and RV stores are usually diluted with water.
The water remaining in the watermaker before the storage procedure will further dilute the
anfreeze, reducing the microbial protecon and increasing the temperature at which the
mixture will freeze.
Anfreeze labeled “Minus Fiy” is a 25% soluon and will begin to form an icy slush at about
+15Degrees F (-10C) and will only provide burst protecon to about Zero F (-18C). Aer a
further 50% percent diluon by water remaining in the watermaker, “Minus Fiy” anfreeze
will only protect from bursng down to about +25F (-4C). Therefore if low temperature
freezing protecon is required a 60% or stronger anfreeze should be used. 60% soluons are
labeled “Minus 100” and will provide burst protecon to -15F (-27C) even aer a y percent
diluon with residual water. “Minus 200” formulaons are pure propylene glycol.
Maintenance - Cont.

38
Introducon to Spectra Chemicals - Cont.
Complete microbial protecon requires a 25% soluon of propylene glycol, so care must be
taken that the soluon remaining in the watermaker during long term storage is at least 25%,
even if freeze protecon is not required. For these reasons Spectra recommends that all
pickling be carried out with a 60% or greater concentraon.
See Winterizing with Propylene Glycol.
Propylene glycol can be dicult to ush from a membrane, especially aer extended storage
periods. This results in high salinity water (high PPM) and residual avor in the product water.
We recommend ushing the system WITH THE PRESSURE RELIEF VALVE OPEN for 4-6 hours
aer storage with propylene glycol—the longer the beer. If, aer extended ushing, you sll
experience low product water quality, cleaning with SC-2 usually removes all traces of
propylene glycol and returns the salinity to the level it was before storage with propylene
glycol. See the Membrane Cleaning Procedure.
Cleaners
Avoid unnecessary cleaning, and avoid cleaning as a diagnosc tool.
SC-2 is an alkaline cleaner used to remove light oil, grime and biological growth. It is most
eecve if heated to 120 deg. F (49 deg. C). In most cases the water quality will increase in
PPM (salinity) aer an SC-2 cleaning. Aer a few hours it should recover to near the level it
produced before the cleaning.
SC-3 is an acid cleaner used to remove mineral and scale deposits. In most cases this is used
rst and if there is no improvement, go on to the SC-2 cleaning. SC-3 will in most cases lower
the product PPM and overall pressures. Scaling is a slow process that may take several months
or years.
For cleaning with either SC-2 or SC-3, see Membrane Cleaning Procedure.

Storage Procedure
1. Close the intake seacock.
2. Push the Fresh Water Flush (FWF) buon to fresh water ush the system. Perform a second
fresh water ush in the same way.
3. Remove the quick disconnect ng from the brine discharge outlet of the Clark Pump, per
photo below, and replace it with the quick disconnect brine discharge service hose. Lead the
brine service hose into the bucket.
4. Push the FWF buon and run the feed pump unl you have one gallon of fresh water in the
bucket from the brine discharge service hose, then press Stop.
5. Mix 1 container of SC-1 storage compound with the water in the bucket. It may not dissolve
completely, which is normal, and any undissolved parcles will be caught by the prelter.
6. Remove the hose from the “to strainer” pigtail on the feed pump module and install the inlet
service hose from the service kit, per photos below. Lead
this hose into the 5 gallon (20 liter) bucket as well.
7. Make sure the pressure relief valve on the Clark Pump is
OPEN (un-pressurized) by turning 1/2 turn
counterclockwise
8. Turn on the feed pump by moving the manual control
switch on the control box to ‘SERVICE’. The soluon will be
drawn from the bucket with the service hose, and
returned to the bucket from the brine discharge service
hose. Circulate the storage chemical in the system for
approximately 20 minutes. Stop the feed pump by moving the switch back to the ‘RUN
AUTO’ posion.
Clean Up
Remove the brine discharge service hose from the Clark Pump, and replace the brine discharge
hose that leads to the thru-hull. You may now pump the bucket dry by moving the manual
control switch on the Control Box back to ‘SERVICE’. Stop the feed pump by moving the switch
back to RUN AUTO.
Remove the inlet service hose and reaach the hose from the sea strainer to the “To Strainer”
pigtail on the manifold at the Feed Pump Module. Drain and clean the strainer and any lters in
the system. Reassemble dry. Leave the pressure relief valve open, since the next me you run
the system you will need to purge the storage chemicals with the system unpressurized. Turn o
the power to the system.

Winterizing With Propylene Glycol
See descripon of propylene glycol formulaons, and purging from system.
1. Close the intake seacock.
2. Push the Fresh Water Flush (FWF) buon to fresh water ush the system. Perform a second
fresh water ush in the same way.
3. Remove the hose from the “To Strainer” pigtail, install the inlet service hose from the service
kit, and lead the hose to the boom of a bucket. Connect the brine service hose, and run it
into a second container.
4. Pour 1 gallon (4 liters) of propylene glycol of appropriate
concentraon (see pages 42-43) into the bucket with the
intake service hose.
5. Make sure the pressure relief valve on the Clark Pump is
OPEN 1/2 turn (un-pressurized).
6. Run the feed pump by switching the manual switch on the
control box to ‘SERVICE’ unl about a gallon of water has
owed from the brine discharge service hose, or anfreeze
appears. Propylene glycol will look slightly dierent, and
feel more slippery, than water. Stop the pump by moving
the switch back to ‘RUN AUTO’. Add more propylene glycol to the intake bucket if necessary.
7. Lead the brine discharge service hose into the intake bucket of propylene glycol. Move the
switch back to ‘SERVICE’. The service hose will now draw propylene glycol soluon from the
bucket, and the brine discharge service hose will return it. Run the feed pump and circulate
the propylene glycol for 20 minutes.
8. Stop the feed pump by switching the toggle switch back to ‘RUN AUTO’. Drain the seawater
strainer, the hose leading to the boost pump module, and the hose between the boost pump
module and the feed pump module. Disconnect the product tubing from the membrane
housing and blow residual water out of the tubing. Empty the charcoal lter housing and ush
water lines. Leave the pressure relief valve open, since the next me you run the system you
will need to purge the system unpressurized.
Your watermaker is now protected from freezing and biological growth and freezing for one year.

Membrane Cleaning Procedure
Spectra cleaning compound (SC-2 or SC-3) must be mixed with fresh water at a rao of 1 container of
compound to 3 gallons (12L) of unchlorinated water. A Catalina 340R system requires one container of
compound per cleaning.
1. Close the intake seacock.
2. Push the Fresh Water Flush (FWF) buon to fresh water ush the system. Perform a second
fresh water ush in the same way.
3. Remove the quick disconnect ng from the brine discharge outlet of the Clark Pump, and
replace it with the quick disconnect brine discharge service hose. Lead it into a 5 gallon (20
liter) bucket. Push the Fresh Water Flush (FWF) buon and run the feed pump unl one gallon
of fresh water runs into the bucket from the brine discharge service hose. Press Stop.
4. Remove the hose from the “To Strainer” pigtail and install
the inlet service hose from the service kit. Lead both hoses
into the bucket.
5. Make sure that the pressure relief valve on the Clark Pump
is open (un-pressurized).
6. Mix the cleaning chemical in the bucket. If possible, heat the
soluon to 120 F (49 C).
7. Move manual switch on the Feed Pump Module to SERVICE
SYSTEM. The intake service hose will draw soluon from the
bucket and the brine discharge service hose will return it.
Circulate the soluon through the system in this manner for 45 minutes. Stop the pump by
moving the toggle switch back to ‘RUN AUTO’.
8. If the soluon cannot be heated, allow the soluon to sit overnight before proceeding to the
next step.
9. Replace the brine discharge overboard hose and run the pump unl the bucket is empty by
moving the manual switch to ‘SERVICE’. Return the switch to ‘RUN AUTO’.
10. Follow the New System Startup procedures to ush the chemicals out of the system (DO NOT
CLOSE the pressure relief valve!)
11. The system may now be restarted, ushed, or stored.

Catalina 340R Flow Test
The ow test is the most useful diagnosc test for system performance, and should be done
before replacing or cleaning your membrane. Changes in producon or water quality are
normally caused by something other than the membrane, unless the system has been le
unused for a long me.
Before the ow test, change all lters and clean the sea strainer. Carefully check for water or
air leaks, as air in the system will cause low producon and errac salinity. Look for air bubbles
in the product ow meter, feed water hoses, and brine overboard hose.
Run the system and watch the feed pressure very closely. If the feed pressure to the Clark
Pump is asymmetrical from one stroke to another, this impedes performance. A dierence of
a few PSI is acceptable, but anything over that is an issue. If the pump is asymmetrical, Clark
Pump repairs should be done before connuing with these tests.
If no asymmetry is noted, connue with this test.
You will need a graduated bucket, either a graduated pitcher or large measuring cup, and a
stopwatch. Log the voltage at the feed pump at the same time. Confirm at least 12.5 Volts at
the feed pump on 12-Volt DC systems.
Take two measurements and compare them with the table on the following page. The first
measurement is the product flow alone. The second is the product flow combined with the
brine discharge flow to get the total flow or feed flow. You may take these measurements by
two methods:
1. Time the product flow into a graduated pitcher, then divert both the product flow and brine
discharge together into a bucket, timing them to measure total flow.
OR
2. Divert the product flow into the pitcher while diverting the brine discharge into the bucket.
Time the flow of both at the same time. After calculating the product flow, pour the pitcher of
product into the bucket of brine to measure total flow.
The ratio of product flow to total flow gives us our recovery rate, as a percentage. If the
percentage is below the minimum it indicates an internal leak in the Clark Pump.

47
1. Product Flow: Product flow is expressed in Gallons Per Hour (GPH) or Liters Per Hour (LPH), by
this equation:
3600 ÷ time in seconds x quantity of water in gallons or liters = GPH or LPH
There are 3600 seconds in an hour.
Example: It took 3 minutes and 35 seconds to collect 1 gallon of product water.
3600 ÷ 215 x 1 = 16.74 GPH (3 minutes, 35 seconds is 215 seconds)
Example: It took 2 minutes and 25 seconds to collect 2.5 liters of product water.
3600 ÷ 145 x 2.5 = 62.07 LPH (2 minutes, 25 seconds is 145 seconds)
2. Total Flow or Feed Flow: Feed flow or total flow (brine + product) is expressed in Gallons Per
Minute (GPM) or Liters Per Minute (LPM) , by this equation:
60 ÷ time in seconds x quantity of water in gallons or liters = GPM or LPM
Example: It took 1 minute and thirty-seven seconds to collect 5 gallons of total flow.
60 ÷ 97 x 5 = 3.09 GPM (1 minute, 37 seconds is 97 seconds)
Example: It took 53 seconds to collect 12 liters of total flow.
60 ÷ 53 x 12 = 13.58 LPM
3. Recovery Rate: Product Flow ÷ Total Flow = Recovery Rate %
Example: 6.5 GPH product flow = .063 or 6.3%
1.7 GPM total flow x 60
(you must first multiply total flow by 60 to convert from GPM to GPH)
*pressure relief valve open ½ turn
In order to make good quality product water, you need the proper amount of feed water ow, as
in the table below. Compare the product ow to the total feed ow. Product ow should be 9.0%
of total ow for a Catalina 340R. If product percentage is low, you may have an internal leak in the
Clark Pump.
For every
1
/
10
th
of a GPM feed water ow loss, we will lose about
1
/
2
gallon per hour of product
ow and the salinity will go up 100 PPM.

Poor Product Water Quality
With any product water quality issue, you must ensure accurate calibraon if you are using a
salinity meter. For general quality evaluaon, your taste is always good enough.
Membranes are not an exact science and two idencal systems can have dierent product
quality. World health standards deem water of up to 1000 PPM of total dissolved solids
acceptable for drinking. We consider any thing below 750 PPM acceptable but not ideal, and
anything below 500 PPM excellent. Factors that could aect water quality are addressed
below.
LOW SYSTEM FLOW OR PRESSURE will equate to lower product quality (higher PPM).
Catalina systems, which have a higher feed to output pressure rao (See nominal
pressures under Flow Test, page 43), as well as a higher feed ow/membrane area
rao, will produce water in the 150-300 PPM range.
DAMAGE TO THE MEMBRANE by chlorine contaminaon. Flushing the system with
chlorinated water will irreparably damage the membrane. Charcoal lters are used to
absorb any chlorine which might be present in ush water. They must be of proper
specicaon to be suitable. See page 48. There is no test for chlorine damage except
the process of eliminaon of other causes.
DIRTY OR SCALED membranes. A dirty (foreign material), scaled (mineral deposits), or
contaminated (bacterial growth) membrane can result in poor water quality and
abnormal operang pressures. If operang pressures are above normal, then cleaning
is indicated. If the system pressures are within operang normal range, cleaning may
have lile result. Avoid cleaning as a diagnosc tool. Low water quality aer storage
with propylene glycol can usually be remedied by extended ushing or an SC-2
cleaning.
MECHANICAL LEAKAGE within the membrane pressure vessel. This is an unlikely but
possible cause of poor water quality. A pinched or damaged O-ring within the
pressure vessel, a scratch on the product tube on the membrane, a scratch within
one of the end caps, or a seal fouled by contaminaon could allow sea water into the
product water.
If system total ow (product plus brine) is 2.7 GPM (10 liters) or above, the membrane is
clean, the product ows are consistent with the system ow and the water quality is sll not
acceptable, then replacement of the membrane is indicated.

Technical Bulletins
The following pages include Spectra’s most commonly-used technical bullens, covering tests,
adjustments, troubleshoong, and common points of confusion. Many more technical
bullens are available on the Spectra website, www.spectrawatermakers.com.
ACCUMULATOR PRESSURE
Your Catalina 340R is supplied with a pressure accumulator tank (PL-ACC-TK) installed in the
feed water line between the feed pump and the Clark Pump.
The purpose of the feed line accumulator is to reduce the spikes in the feed pressure caused
by the cycling of the Clark Pump. If the accumulator is not properly charged it can lead to
pressure spikes and system shut down. The accumulator has a Schrader air valve, like a car
re, which allows the internal air bladder of the accumulator to be pre-charged. The
accumulator should be pumped up to about 60 psi (4.1 bar) for best results. Add air using a
re pump or air compressor. You can experiment with the exact pressure that will give the
best pulsaon dampening on your installaon.

PREFILTERS
It is important to remember that your Spectra Watermaker is designed to process clean, open-
ocean seawater. Any departure from that standard for your seawater intake runs the risk of causing
excessive wear or damage to internal pump parts and/or the vulnerable reverse osmosis mem-
brane. Addional preltraon consideraons and/or extremely frequent prelter replacements may
be required in any deviaon from open-ocean seawater. Your local service provider or installer may
have specic recommendaons based on their experience with water condions unique to your re-
gion.
Observe the seawater around your vessel. Is it clean enough to use for your seawater intake? There
are several things to avoid feeding to your watermaker:
• petroleum products, such as oil, fuel, thinners, paints, paint removers, etc.
• chlorine-treated water; e.g., most “dock” water
• silty water — water contaminated by ne, hard, suspended parculates
• putrid water, “red des”, or any seawater that smells or looks contaminated
• harbor/marina water that you cannot see through or that shows visible signs of
contaminate (neighboring boats docked nearby may be discharging contaminaon!
Sewage, chemicals, etc.)
Judging the quality of seawater input always involves a certain calculated risk. We know of watermak-
er systems that have been destroyed far oshore by intaking fresh whale excrement or oil contami-
nants from natural seepages. The chance of such things happening is normally small but should be
considered. On the other hand, regularly running a watermaker in an enclosed marina or harbor
runs a much higher risk of harmful contaminaon. If you need to test a new installaon while in a
marina or harbor, monitor the water quality around your vessel carefully while tesng. Oen mes
you should be able to run the watermaker safely for enough me to briey check out the system if
you are mindful of external feed condions. If this is not possible, an arcial ocean is a useful
alternave (see Page 29 for arcial ocean tesng/instrucons). Don’t sail away without tesng a new
installaon or repair!
During normal operaon, the feed water is ltered in two stages. First it passes through a ne mesh
metal sea strainer, which protects the feed pump from foreign materials and sea creatures. Aer
passing through the feed pump, the feed water passes the lter housings containing 20 and 5
micron elements, removing very ne parcles that could damage the Clark Pump and shorten
membrane life. An addional carbon lter prevents the entrance of chlorine during fresh water
ushing (see next page).
Prelter maintenance schedules will vary widely depending on how and where the system is used. If
large amounts of feed water are run through the system over a relavely short period of me in
biologically ferle near-shore waters, the prelters will plug up, water producon and quality will
drop, and the system pressure will change dramacally. In blue water condions the prelters may
only need to be changed every week or two.
When operated for only an hour or two a day in inland or near-shore waters, the trapped plankton
will begin to decay in the lters long before the elements plug up. The decaying plankton and
bacteria will cause a roen egg smell in the product water. This decay will set in overnight in tropical
waters, or aer a week or two in higher latudes

51
CHARCOAL FILTERS
The charcoal lter element (FT-FTC-CC) removes chlorine from the fresh water ush water supply, as
the RO membrane can only handle small amounts of chlorine without permanent damage.
The charcoal lter used for the fresh water ush system will not plug up unless you have very dirty
domesc water in your boat’s supply tank.
The charcoal lter we supply removes 99.7% of the chlorine. Beware when buying other charcoal
lters. If they don’t specify the percentage of chlorine removed, don’t use them. Cheap ones may
remove only 60% or 70%. Also, there are aermarket lters which are very close to, but not exactly,
the right dimensions, and they will not seal in the housing. If you skimp on the charcoal lter you risk
damaging a $600.00 membrane on the rst ush. The other factor is the ow rate that the lter can
handle. Because the chlorine is adsorbed by the charcoal, it must remain in contact with the charcoal
for a sucient period of me for the all of the chlorine molecules to be captured. The lters we use
can handle 1.5 gallons (6 liters) per minute ow, and are good for 3000 gallons (12,000 liters) at 1.5
GPM, or six months, whichever comes rst. Regardless of the amount of water treated, the charcoal
loses its eecveness aer six months.

Optional Z-Ion Protection System
The Z-Ion, developed by Spectra, protects the enre system from fouling for extended periods
without fresh water ushing or storage chemicals (pickling).
The Z-Ion achieves this end by introducing a stream of metallic ions into the fresh water ush
water, thus ooding the enre system with ions that prevent biological growth for up to thirty
days. If you are going to let your system sit idle for longer than thirty days, you will sll need to
treat it with SC-1 storage chemical or propylene glycol.
The Z-Ion will not prevent freezing, so in freezing climates pickling with propylene glycol is sll
required. Even with the Z-Ion there may sll be cases when you need to pickle your system
with SC-1 storage chemical or propylene glycol, so we recommend you carry one of these
products at all mes.
If your system was ordered with the Z-Ion, it will require only some basic wiring and
commissioning, laid out in the following pages.
If you didn't order you system with the Z-Ion, it can be retroed to any Spectra system.
NOTE: Contact Spectra for more informaon at: techsupport@spectrawatermakers.com

The Z-Ion should be energized at all mes, but will only consume power when operang. Upon
inial power-up the LED will ash red/green and then will turn solid green.
Follow the instrucons for Normal Operaon and Fresh Water Flush. For treatment with the
Z-Ion, the process is idencal, only the Z-Ion will release silver and copper ions into the ush
water when you turn on the generator with the on/o switch. Turn on the ion generator at the
same me that you open the ush valve.
The operaon cycle begins and the LED will ash green/amber. The cycle will connue unl you
turn o the ion generator or the adjustable mer mes out (factory set for 15 minutes).
Turn o the ion generator at same me that you close the ush valve. If you forget to turn o
the ion generator, the Z-Ion will me out aer 15 minutes, so no harm will be done to the unit.
If the voltage is out of range, below 10V or above 56V, the LED will ash red every two seconds
and the unit will shut down.
Each fresh water ush with the Z-Ion will protect your watermaker for up to 30 days, aer
which the process must be repeated.
Aer 720 cycles the service light on the front of the control box will light up, indicang that the
probes on your Z-Ion may be wearing down, and should be tested. The service light is just a
reminder, and the Z-Ion will go on funconing while it is lit.
